MACHINE FOR JUSTIFYING TYPE;

SPECIFICATION forming part of Letters Patent No. 695,017, dated March11, 1902. Application filed June 29, 1901. Serial No. 66,621. (Nomodel.)

To all whom it may concern;

Be it known that I, JOHN W'ATSON, a citizen of the United States, and aresident of Brooklyn, county of Kings, State of New York, have inventeda new and useful Improvement in Machines for J ustifying Type,of whichthe following is a specification.

My invention relates to an improvement in devices for diminishing theimpact of the lineholder in its descent when moved by gravity inmachines of the character of that described in application for LettersPatent, Serial No. 24,291, filed July 20, 1900, the invention of FrankMcOlintock, and it relates particularly to devices which act on theline-holder for a limited time only and do not prevent the free movementof the line-holder thereafter on its line of travel through the line.

The invention will be best described by reference to the accompanyingsheet of drawings, in which-- Figure 1 is a side elevation of theportion of a justifying-machine to which this improve ment is attached,and Fig. 2 is a sectional "iew on the lines A B of Fig. 1.

Similar letters refer-to similar part-s throughout the several views.

In the drawings, f is the side plate of a typejustifying machine of thecharacter of'that referred to in the aforesaid application. 0 is theline-holder. t' is the top plate. b is the upper channel, having asuitable inclination in which the line-holder travels downward bygravity. e is the series of space-bars assembled in the line-holder; .2,the type-characters, also assembled therein. 13 is the opening in theside plate, through which the thinner ends of the space-bars project.These parts are common to all machines of the character shown anddescribed in the application above referred to. In the presentconstruction a second opening15 in the platef is provided below theopening 13, as shown in Fig. 1, and the line-holder is provided on itsface with a longitudinal slot 14, commencing a convenient distancebehind the front end ofihe line-holder and extending to its extremerear. The slot 14: is cut longitudinally on the face of the line-holder,so as to be opposite the opening 15. Attached to the plate f is a bentplate 3, provided with openings 12 and suitable screw 11, which enableit to be shifted upward or downward, as may be desired, and thensecurely attached thereto. Attached to the upper face of this plate is alever 1, pivoted at the point 2 and controlled, so far as its forwardmovement is concerned, by a stop 4: on the plate 3 at its rear end. Thefront end of the lever 5 is beveled, as shown in Fig. 2, so as to fitinto the slot 14 in the line-holder c after the device has operated. Thebackward motion of the lever is controlled by means of a springpassingover a pin 16 on the end of the lever. The other end of the spring abutsagainst the disk on the screw-pin 10. The tension of the spring may beincreased or diminished, asmay be desired, by turning the thumb-screw10.

The method of operation is substantiallyas follows: Upon the release ofthe line-holder c by the operator after filling it moves down the trackor way b by the action of the force of gravity, necessarily withincreasing momentum. As soon as it reaches the projecting end 5 of thelever 1 it forces the end of the lever to the right, compressing thespring 16. Thereu pen the friction existing between the end of the lever5 and the side of thelineholder at the point 17 retards the downwardmovement. When the full portion 17 of the line-holder c has passed theend of the lever, the latter is thrown forward into the slot 14: bymeans of the spring 9, and thereafter it ceases to perform any functionand leaves the line-holder entirely free to continue its travel down theinclined track I) by the action of gravity. The tension of the spring isadjustable and may be made such as to retard the movement of theline-holder sufliciently to make the operation satisfactory.

I claim as my invention- 1. The combination of a line-holder arranged.to descend by gravity, and a device for diminishing the impact of theline-holder and retarding its movementsubstantially as described.

2. The combination of a line holder arranged to descend by gravity, aside plate against which it slides; and a device on the side plate fordiminishing the impact of the line-holder and retarding its movementsubstantially as described.

3. The combination of a line-holder arranged to descend by gravity, aside plate against which it slides; and a lever arranged to engage withthe line-holder and retard its movement, and devices substantially asdescribed for controlling the movement of the said lever.

4. The combination of a line-holder arranged to descend by gravity, aside plate against which it slides, and a lever pivoted on the sideplate arranged to engage with the line-holder and retard its movementand de vices substantially as described for controlling the movement ofthe said lever.

5. The combination of a line-holder provided with a slot of suitablelength upon its inner face, a side plate against which it slides; and alever pivoted upon the side plate of the machine, the forward end ofwhich is arranged to engage with and retard the move ment of theline-holder as it descends, and devices substantially as describedwhereby after the forward end of the line-holder has passed the point ofthe lever, the point is forced forward into the slot and ceases tooperate.

6. The combination of a line-holder provided with a slot of suitablelength on its inner face; a side plate against which the line- JOHN\VATSON.
